Arrange the four graphs in descending order of total work done; where $W_{1}, W_{2}, W_{3}$ and $W_{4}$ are the work done corresponding to figure $a, b, c$ and $d$ respectively.

Question

Arrange the four graphs in descending order of total work done; where W 1 , W 2 , W 3 and W 4 are the work done corresponding to figure a , b , c and d respectively.

As seen from figure, work done in first graph, $W_{a} = 0$ .

Now, work done in figure $b$ , $W_{b} = + ve$ , and that in figure $c$ , $W_{c} = + ve$ , $> W_{b}$ .

In last graph, work done is $W_{d} = - v e$ .

So, the descending order of total work done is

$\Rightarrow W_{c} > W_{b} > W_{a} > W_{d}$

$\Rightarrow W_{3} > W_{2} > W_{1} > W_{4}$
